Brennan Discovers Ostrich Erection Mechanism

A recent article by Patricia Brennan (UMass Biology Dept.) and Richard Prum (Yale University) has received considerable press attention. The Journal of Zoology paper, entitled on the "Erection mechanism of the ratite penis," reports that ratites (large flightless birds including the ostrich and emu) have a lymphatic erection mechanism. The finding solves the long standing mystery of how the penis of large ratites functions and suggests that lymphatic erection evolved in the last common ancestor of birds.

Press coverage of the paper includes news articles from the BBC and Nature.
